This image confirms dark spot imaged by Anthony Wesley on July 19.

[Sergio Saltamonti,Livorno (Leghorn,Tuscany,Italy)]

Here are my images from last morning. Conditions were fair but not excellent for
the 26 deg. altitude. I  took IR/B pairs at approximately 20 minute intervals.
Initially I was interested in the GRS and the Io transit and shadow transit,but
my attention was also caught by the unusual dark spot in the south polar region.
I observed visually from about 02:10 to 02:30 with binoviewers and could clearly
see the dark spot,as well as the orange Io against the equatorial zone.

It was not until the afternoon that I got news of Anthony Wesley's discovery of
the suspected impact site. I agree that it does look very like a smaller version
of the Shoemaker-Levy impact,with the dark red colouring and the smeared
appearance. I hear that Andrew Robertson and Mark Turner also observed it
visually from Norfolk at the same time,and Ian Sharp imaged it from Sussex.

My images are presented as sets of IR 742nm,blue and I(synth. G)B images.

Here is Jupiter,Io and its shadow in transit on 2009/07/20.
There is a new dark spot in the SPR.

A quick and dirty Red and Green channel from a very low Jupiter at around 10pm local time.
Now to chase the rain away.  Anyone would think this is England

夕方から梅雨の晴れ間が出てきたので、今話題の衝突痕をみたいと思い、
早い時間から準備しましたが、隣家の立木に邪魔され、撮影出来ませんでした。
そうしているうちにまた雲が出てきて撮像は約１時間で中止になりました。

My first observation of the impact mark.
